In regards to what you're saying, it's relatively safe as long as you behave yourself.
I looked into it once, you have to go through companies in Beijing, it's insane, you have to get a multi-entry Chinese visitors visa and go to the companies office in Beijing, they apply for your visitors visa to North Korea on your behalf, you only know 24 hours prior whether you will be allowed into the country.
Once you're there, it'll literally be the safest trip you will ever take, but pickpockets are the least of your worries, the authorities are very touchy and essentially you do what you're told and keep your mouth shut and you'll be fine.
It could be viewed by the state as foreign propoganda meant to incite anti-revolutionary sentiment among the hotel staff or something.
As I said the North Korean authorities are very touchy, even a picture taken at a wrong angle of images of the leaders can lead to trouble, usually for the tour guide and not the tourist but let's say he did even bring the bible with him, it was a stupid mistake.
Though you can never trust the NK authorities, they may be doing this as part of a bargaining strategy.

The only moral question I have to wrestle with is the fact that by going there I am indirectly providing a source of revenue to a regime I despise.
